Elijah I think the best way to pass info on to younger people is start when they are young. By the time they are 15 they already know everything . You can only share with ones who are ready to listen. Some older ones will be ready because they are interested and others will be forced by circumstance in SHTF. Just be ready to share when the time presents itself. The best place I can think of would be to start a young boys camping group at your church or maybe become a Scout leader. As interest builds get a few of the dads to join in to “help” and teach them too.
